  Again... we don't give documentation and examples for every possible situation.  If that isn't clear by now, I don't know what else to say.

  Are you reading the Cisco documentation as I suggested?  The RFCs are nice but they're not the Cisco documentation.

  Does the Cisco documentation say to return those attributes for assigning two VLANs?

  What does the debug output say?  Is it returning those attributes to the switch?

a) yes - consult the Cisco documentation to see which attributes are needed, and what values they should have

b) no - read the FreeRADIUS documentation to see how to configure FreeRADIUS to send attributes in an Access-Accept. There are many, many, examples.

  The problem here is that you're stuck on "I need to configure 2 VLANS".  That's a high level requirement, and it doesn't help you configure FreeRADIUS.

  I'm asking you to break down the problem into pieces, and solve each piece in isolation.  So far, your response has been "no, I'm not going to do that".

  It looks like I can't help you.
